First, a coil-shaped corrugated plate and a flat plate are set. That is, the coiled corrugated plate is attached to the corrugated plate supply reel 3a, and the coiled flat plate is mounted to the flat plate supply reel 3b and supplied to the pinch rollers 7a, 7b, 7c and 7d. The flat plate is fed by the flat plate feed motor 4, and the motor is started / stopped depending on whether or not the flat plate detection sensor 5 detects it, so that the slack of the flat plate between the supply reel and the pinch roller is made uniform. The air cylinder 10b is operated to pinch the flat plate with the pinch rollers 7d and 7b.

In this state, the air clutch is set to a predetermined pressure to drive the motor, the flat plate advances in the flat plate transport guide 13, and the motor is stopped by the detection of the steel strip positioning sensor 25a. Next, the steel strip straightening cylinder 17a descends, the upper surface of the steel strip is pressed by the straightening jig 17b to straighten the bend and the like, and then the binding jig 19 restrains and fixes it on the transport table 18.

The flat plate pinch roller 7d and the steel strip straightening cylinder 17a are retracted, the motor 24 is driven, the transport table 18 is advanced to the winding position, and the transport positioning sensor 25b drives the motor 24.
Stop. At the same time, the winding motor 77 is driven, and the rotary shaft origin sensor 25c makes the rotary shaft 26 horizontal.

Then, the main body positioning motor is driven to perform positioning in the width direction. In this state, the rotary shaft operating cylinder 32 is operated to insert the steel strip into the slit portion 78 provided in the rotary shaft 26 and sandwich the entire width from both sides of the steel strip. Pinch the flat plate with the pinch roller 7d by operating the air cylinder 10b, then retract the transport table 18, the pinch roller 7a, the corrugated plate feed auxiliary roller 14, operate the guide plate operating cylinders 70a, 70b, and pass the plate guide plates 69a, 69b. Thus, the end faces of the flat plate and the corrugated plate are aligned near the winding.

The air of the air clutch of the flat plate feed motor is released, and a constant voltage is applied to the brake 9. The winding motor 77 is driven to start winding, and the flat plate starts winding so as to wind the corrugated plate, and tension enough to fit and wind around the outer circumference of the rotary shaft 26 is applied.
Apply with brake 9.

Next, when the initial winding shape is formed, the rotating shaft operating cylinder 32 is operated so as to move backward by one step, and the rotating shaft 26
Pull out halfway and continue winding. This is advantageous for removing the rotary shaft 26 after winding.
Here, the side guide operation cylinder 39 is turned on and off at a constant pitch, the side guide plate 27 is continuously opened and closed, and the end faces are aligned while winding. Gradually increase the speed of the winding motor 77 and wind while controlling the tension. At the same time, the bus line adjusting cylinder 68 is operated. After winding a certain length, cut the flat plate and the corrugated plate.

At this time, the dimension adjusting roller lifting cylinder 65, the dimension adjusting cylinders 60, 63 are operated at a low pressure, and the dimension adjusting rollers 44a, 44b, 44c, 44d, 44e, 44f are brought into close contact with the winding outer periphery,
It is a material that can be wound so as not to loosen after cutting. Then, after the diameter and circumference are measured, if necessary for dimension adjustment, a constant pressure is applied to the outer circumference by dimension adjustment rollers 44a, 44b, 44c, 44d, 44e and 44f. Dimension adjustment rollers 44a, 44b
Is a belt wrapper system that allows rotation from the outer circumference.

Here, the rotary shaft 26 is pulled out, and the side guide plate 27 supports the end face to perform the dimension adjusting operation. That is, while applying pressure to the outer circumference, the winding motor 77 is rotated while the outer circumference is rotated by the belt wrapper and the end surface is supported by the side guide plate 27, and the tightening dimension is adjusted. Alternatively, it is also possible to adjust the tightening dimension by providing a speed difference between the two.

The winding diameter or circumference is detected by the sensor, and the dimension adjusting operation is completed when it reaches a predetermined value. The outermost periphery is fixed by spot welding, etc., and all operating functions are retracted to complete the work.

In addition, even when the winding diameter is small, the size adjustment rollers
It is also possible to wind by driving the outer circumference by the belt wrapping method of. The winding diameter can be dealt with by the winding diameter following cylinder 50 and the motor 72.

[Effects of the Invention] As described in detail above, according to the device of the present invention, the flat plate and the corrugated plate are alternately arranged and automatically wound into a honeycomb shape by a machine, so that the quality can be stabilized and the work efficiency can be improved. Efficiency, and its effect is extremely large.
